目的探讨实时三维超声(又称四维)在诊断胎儿体表畸形中的应用价值。方法回顾性分析76例经超声诊断胎儿存在不同程度畸形病例,并经产后证实,所有检查均包含应用了实时三维与二维超声,分析二维及三维超声提供的畸形部位、形态,并比较二者超声诊断与产后诊断的符合率。结果产前76例胎儿诊断体表畸形83处,产后证实畸形87处,二维超声诊断与产后诊断相符的有68处(符合率78.16%),实时三维超声诊断85处(符合率97.7%),二者比较有显著性差异(P<0.05)。结论实时三维超声成像较二维超声成像更直观准确,能够提供二维超声无法提供的更多、更准确的信息,在产前诊断方面具有一定的临床应用价值。
Objective To explore the value of real-time three-dimensional ultrasound (also known as four-dimensional) in the diagnosis of fetal surface deformity. Methods A retrospective analysis of 76 cases of fetal ultrasound diagnosis of fetal malformations of varying degrees, and confirmed by postpartum, all checks include the application of real-time three-dimensional and two-dimensional ultrasound, two-dimensional and three-dimensional ultrasound analysis of malformations, morphology, and compare two The coincidence rate of ultrasound diagnosis and postpartum diagnosis. Results There were 83 prenatal diagnoses of fetal malformations in 83 fetuses and 87 deformities in postnatal period. There were 68 coincidences (78.16%) in two-dimensional sonographic diagnosis and 85 postnatal diagnoses, with a real-time three-dimensional sonography of 85 (97.7%) , There was a significant difference between the two (P <0.05). Conclusion Real-time three-dimensional ultrasound imaging is more intuitive and accurate than two-dimensional ultrasound imaging, which can provide more and more accurate information that 2D ultrasound can not provide. It has certain clinical value in prenatal diagnosis.
